Kei is very tall and has an incredibly slim build for a volleyball player. He plays middle blocker for the Sendai frogs. He has short blond hair, golden-brown eyes, and he wears glasses. Kei's personality is quite blunt and salty, but he can be genuinely nice if he so wishes. Kei is autistic and his special interest is dinosaurs. He stims with his hands most of the time and especially when he's nervous. He doesn't get meltdowns easily, but he has his noise canceling headphones on him always.
